all 'who/m t may concern? I e it lrnoivn that l, @nanars Cnoivnnn, a lcitizen et the United States, and resident ol' the borough of Brooklyn, county of lngs, city and State of New York, have made a certain nevi7 and useful invention ltelating to Processes of Making rCloth Gumined Tape, of Twhich the following is a speciiication, talren in connection with the accompanying drawing, which furnis part ot the saine.

rlhis Ainventioifi to relates p especially Y guninied tape such as niay be used tor seal ing cartons, packages, or for other in Twhich the relatively narrow y also stronger and tirnier than 'the advancing a web ot' such guniined cloth intermittently a distance equal to the Width of the guniinedstrips desired these strips may he successively several@ 'ered transversely to the length of the web so that the stronger ivarp threads are arranged transversely to and preferably substantially perpendicularly to the length of the gununed strips so that they have a maxiinuin et transverse strength, and if desired, the gurnnied strips may he fed or rnoved transversely across the end of the web troni which they are cut and tened so that they are delivered in condition tor use.

The accompanying diagrammatic draW ing shows in Figure l a perspective vieivof an arrangement for severing gumined strips troni one or more Webs.

F 1g. 2 is an enlarged plan View showing the relation of the severed strip tothe web;

and

Fig. 3 is an enlarged diagrammatic section taken longitudinally of the gumnied tape strip.

For sealing and other finishing purposes cloth gumined tape does not in inany cases need a very high degree of longitudinal strength While its transverse strength is considerably more important because the strip is usually employed to cover a seam extending longitudinally of the strip and adhesively hold the edges of this seam together. The number and character of the threads extending transversely of the strip therefore determine its efficiency and strength under.

' or ivoor threads.

b and character as generally simultaneously moissuch conditions While the longitudinally eftending. threads are of relatively little iniportance so long as a fair degree of longitudinal strength is preserved and so long as the strip is not unduly stilened in this Way. For this reason it is desirable to torni cloth gurnrned cloth in which the Y stronger and harder' hecause of the different tvrist given them, but also preferably weven under rnuch greater tension than the hlling ,ln cloth gununedA tape suitable for ordinary package sealing; cloth having Warp and illing threads ot such size, Weight correspond with what are used in print cloths7 may he eniployed and the count ot the Warp threads is preferably niuch greater than that et the filling threads and may advantageously he made about twice as great. llor example, when lilo. 28 or 30 Warp thread is used the warp count may be abeut 60 per inch, While the iilling threads preferably ot inuch softer, vvealrer material, inay be only about 30 per inch which ineans a considerable saving in the Weight and cost et the cloth. lt is also desirable for seine purposes to have the Warp threads stretched considerably tighter than usual during the Weaving process so that they are relatively straighter in the finished cloth, the softer lilling threads having a niore zigzag or irregular arrangement between them. Such specially Woven clothiinust, of course7 be severed into transversely extending strips in order to utilize the strength of the Warp threads t0 best. advantage for guinined tape purposes. lt is also of course apparent that the cloth preferably after having been :filled andfinished in any suitable Way so as to secure the desired degree of imperviousness may be first severed and then rendered adhesive in some cases just beforevits utilization, orthe cloth may be first gumined and then severed into the individual gunnned strips preferably after having been slit into web rolls in which strips troni specially Wovenvvarp threads are not only v *rapid am.
